Issue still reproducible after a period of SVN inactivity. Regards, Alexey.

Since Subversion can't represent the copy as part of the diff it tries to do the interoperable thing which is to represent the addition of a new file (from a copy) as an addition. That's not quite true in general. It's more like: 1) If the copyfrom source is part of the operative revision range of the diff command, show a modification against the copyfrom source. Unless --show-copies-as-adds was passed, because then we always show copied files as an addition. 2) If the copyfrom source is not part of the operative revision range, history of the file isn't traced back to that revision, so it appears as an addition. It could be argued that 2) is weird special case, and that it should behave like 1) (i.e. trace back to the copyfrom source anyway) and only show an addition with --show-copies-as-adds. Johan pointed out that svnlook diff seems to traverse to the copyfrom source even in case 2). If this is indeed the case, these commands are now behaving in contradictory ways :( However, I think it's too late to change either command now. Thanks for bringing up this explanation. So the second inconsistency is because '-c X' actually defines operative range X-1:X and the source of the copy is X-2 in this case. Indeed, a lot of subtleties and inconsistencies that appear to be bugs. Is there ever going to be SVN 2.0 that can finally break these bug-for-bug compatibility promises? Is there a list of things that are going to be changed in 2.0? Regards, Alexey.

E.g. it may not be feasible to trace the back the copy history of every child when diffing two directories. I am not that familiar to say why 'svn diff' behaves in the way it does, but it does look like it's contradicting the description in 'svn help diff': --notice-ancestry : diff unrelated nodes as delete and add Since 'svn diff' does not take the opposite option, '--ignore-ancestry', I'd say one would assume that 'svn diff' should diff *related* nodes textually, not *as delete and add*. Tracing each child may take some additional time, right, but between "fast and wrong" and "slow and correct" behaviors, I'd choose the latter :) Since you know all paths and revisions involved, you could also run: svn diff ^/foobar@1 ^/barfoo@2 Well, either of these approaches is not very convenient when there is a dozen moves & modifications in a single revision. Agreed. At least the file diffs allows you to 'zoom in', but it would be much better if there was a way to get the diff you want to see with just one command. If backwards compatibility of 'svn diff' behavior, or the performance impact of tracing every child, is a concern - is it possible to have 'svn diff' do such history tracing if enabled by some new option? Although, I cannot come up with a better name than 'svn diff --properly-diff-related-nodes'. Besides, the former (just passing the path) does not seem to work in all cases.

Hi, Is it possible to get rid of the lots of "Index:" headers in the output of the 'svn diff' where there is no actual difference between the files?

For example, I copied Linux kernel from one path to another and now 'svn diff' shows the Index: line on each copied path, e.g. $ svn di arch/x86 | head -20 Index: arch/x86/.gitignore === Index: arch/x86/Kbuild === Index: arch/x86/Kconfig === Index: arch/x86/Kconfig.cpu === Index: arch/x86/Kconfig.debug === Index: arch/x86/Makefile === Index: arch/x86/Makefile.um === Index: arch/x86/Makefile_32.cpu === Index: arch/x86/boot/.gitignore === Index: arch/x86/boot/Makefile === As you might imagine, this bloats the patch considerably and effectively makes it unreviwable.

My goal is to make scripts like yours unnecessary. The current implementation does not yet detect moves which happened inside copies, but I hope to get that fixed before release. Thanks, Stefan I gave it a try (r1763039) and it is not different from what I see with 1.9.x: the files that were renamed on the branch are still copied from the branch, not renamed on the trunk. I.e., svn cp $SVNREPO/trunk $SVNREPO/branch/x svn co $SVNREPO/branch/x cd x svn mv foo.c bar.c vi bar.c svn ci cd .. rm -rf x svn co $SVNREPO/trunk cd trunk svn merge ^/branch/x svn info bar.c The last command shows bar.c as being copied, without any changes, from ^/branch/x/bar.c - rather than being copied from ^/trunk/bar.c and modified. And, since there are no changes in the diff, ReviewBoard shows nothing in the diff for bar.c. You'll have to produce some kind of tree conflict involving the renamed file. The run 'svn resolve' (or use the conflict prompt 'svn merge' opens for you). To be clear, 1.10.x will *not* change 'svn merge'. It changes post-merge behaviour during tree conflict resolution only. I'm afraid this won't fix your problem with ReviewBoard. Well, tree conflicts during merge is a separate pain point with SVN, but here I was referring specifically to the reviewability of the merges - so 1.10 will not make this script obsolete, unfortunately. Perhaps, the change in merge behavior can be made conditional on some command line option, e.g. 'svn merge --replay-merged-renames'? Also, I was just made aware that the script I posted has a shortcoming if the branch being merged has been previously merged into trunk, and then had seen more development on the branch (i.e., it is a branch for ongoing development, not "merge-and-delete" branch). Thing is, it is not very straightforward with Subversion to discover *where this file has been copied to*. For example, "I have a file foo.c in revision 111; under which name(s) is this file appearing in HEAD?" I think adding an ability to obtain this kind of information has been discussed in the past - is it on the table for 1.10? Regards, Alexey.

It should show exactly the content-wise difference between TRUNK and BRANCH, so if some content was merged from TRUNK to BRANCH, both should be identical on that point, and it shouldn't show up in 'diff'. That command would also show changes made on trunk that have not yet been merged to the branch. (E.g., if you ran it in on subversion's trunk and 1.9.x branch, it would show -SVN_VER_MINOR 10\n +SVN_VER_MINOR 9\n.) The OP asked for the changes merge would do, which is approximately --old=TRUNK@REV --new=BRANCH where REV is the youngest revision of trunk merged to the branch. ("Approximately" because this is inaccurate when cherry-picks or subtree merges hapepned.) There's one more issue with these approaches. ReviewBoard can be smart about displaying the moved/copied files. However: - If one does 'svn merge --reintegrate', Subversion will copy new files from the branch unchanged, and 'svn diff' will not show them (and hence, RB won't either) - or, with --show-copies-as-adds, it will show them as being added anew. For the review purposes, it would be better if instead of copying the file from the branch unchanged, Subversion would perform the same move on the trunk and apply the textual changes. - If you do 'svn diff --old=... --new=...', I believe the copy-from information is lost from the diff completely - and ReviewBoard will show all the moved files as adds/deletes, not showing diffs either. For now, I am using the attached script to perform this task. The workflow is: 1. Perform a merge to trunk. 2. Run the script (which attempts to find the original location in trunk for every copied file and replay the move on trunk). 3. 'rbt post'. The script is not perfect; it only operates at file level - so if there are renamed directories, the files inside them end up in 'R +' status (replaced with history) and ReviewBoard shows a spurious deletion for this file, in addition to a move/copy with changes.

The difficulty here is that Subversion does not know that the repository tree was created as a commit from this working copy. Resolving the tree-conflicts automatically probably needs more complete move-tracking. I think this kind of conflicts happens with plain deletions as well. I don't have a trunk Subversion available right now to check though. I think theoretically Subversion could work its way up: first it could note that d1/f1 is removed in both local tree and the repository. Since it is the same change, it could then resolve that conflict. Then, seeing no other changes in d1 in the local tree - it could conclude that the deletion of the d1 directory is again the same operation - and resolve that conflict, too. Lather, rinse, repeat for any higher-level directories. Regards, Alexey.

I will get tarred and feathered here for my way of trying to solve this, and possibly even rightfully so, but... ;) Well, I certainly won't skin you alive for suggesting this; but ... I would imagine that git svn fetch has to essentially do just what the OP doesn't want to do, i.e., successively retreive each revision of every file in the Subversion repository to populate the Git repository. There's not much chance this would be faster than just doing the same with Subversion, especially since, once you're done you /still/ have to scan the files resulting Git repo. Going back to the original question ... Aside from the brute-force method of checking out the entire repository starting at revision 1 , performing a scan, updating to the next revision, and repeating until I reach the head, I don’t know of a way to do this. This is, in fact, likely to be (almost) the most efficient way to do this, since you can just use the existing Subversion client to deal with the repository contents and version discrepancies. But there is an alternative that might be more efficient in your case: Create a dumpstream of the repository using svnadmin dump, non-incremental and not using deltas, then pipe the stream to a custom tool that extracts the file contents the stream and either writes them to disk, or passes them to your scanning tool in some other way. The reason why this could be faster than the checkout+repeated update is that you do not have the overhead of a working copy, directory tracking, property handling, etc. etc., and you can probably save on disk space by keeping the file contents around only as long as they're being scanned. It does mean that your custom tool will have to parse the dumpfile format, but that's really not so hard, the format is quite simple, and there are a number of example scripts that do that in our repository. Another alternative is to use our API directly, possibly through one of the bindings, to get file contents straight from the repository; but I suspect it's harder than parsing the dump file. The Python bindings for parsing the dumpstream currently do not work as I described on svn-dev@ some time ago: the layer which does thunking of the C calls back to Python code is not implemented right now. As far as I can see, Perl/Ruby bindings have the same problem. That, and the way to create a stream in Python does not seem to be working - see the email I just sent to svn-dev@ a few minutes ago. Ironically, I found that when I tried to test the implementation of this thunking code for parsing the dumpstream :) Not sure if this affects Perl/Ruby. So, back to your advice - it's either using C library directly, or implementing the parser for the stream. Which isn't hard, I admit. Regards, Alexey. -- Brane

Hope that helps. With the WANdisco builds or any builds? The only differences between 1.8.0 and 1.8.1 that impacts the Perl bindings in any way was shutting up a bunch of compiler warnings about the _ symbol (which Perl defines in their header files and SVN also uses internally for different purposes) and a bunch of documentation changes. Neither of which should have any functional difference. If you're seeing this with the WANdisco builds I think this is something wrong with those builds, which has been my inclination in looking into this. I cannot try stock CentOS, as they don't have 1.8.x available. I did try building and installing 1.8.10 from source on the same machine, and it works fine. So, it doesn't look like a version-specific issue - rather, like a build environment issue for WANdisco subversion-perl RPMs. Is it possible that the build environment changed between 1.8.0 and 1.8.1?

Problem with subversion-perl RPMs from WanDisco?
Hi all, I tried to update subversion to 1.8.10 on a freshly installed CentOS 6.5 and noticed that an attempt to use Perl bindings has failed due to an undefined symbol in the libsvn_swig_perl library: svn_swig_pl_get_current_pool $ readelf -Ws /tmp/usr/lib64/libsvn_swig_perl-1.so.0 | grep svn_swig_pl_get_ 79: 0 NOTYPE GLOBAL DEFAULT UND svn_swig_pl_get_current_pool This symbol is defined in the library packaged into 1.9.0-alpha2 RPMs, but not in any 1.8.x/1.7.x RPMs. I have also tried on another machin - it originally had CentOS 6.0 installed + partially upgraded. There, the Subversion Perl bindings from WanDisco's RPM just coredump in Repos::Open - I am not sure if it is the same issue or not. It works with the original CentOS version of subversion-perl (1.6.x). Regards, Alexey.

Any scalability traps to be aware of (i.e. non-linear increase in time due to increase in size of the property value)? I tried a 4Mb property, seems to work fine... One thing to be aware of is that properties were never designed to be large. Property values are always transmitted in full text between client and server (i.e., they're not compressed); they're stored in full text in the repository (not deltified the way file contents are). So the more large properties you have, and the more often you modify them, the less efficient your repository will be, in terms of storage requirements and network bandwidth. So while you should be able to store a 2 gig property value, I really, really recommend not to do that. I thought of having pre- and post-commit hooks communicate using a *revision* property: pre-commit hook would set a revision property with the list of files and actions to be performed on them, and the post-commit hook will perform these actions by committing a new revision (instead of modifying a transaction by pre-commit hook). Thus a more specific question - when are arbitrary *revision* properties sent from the client to the server? Obviously, svn:* properties are used by various SVN commands; but am I right to assume that non-standard revision properties are sent only for the 'svn pg --revprop' command? That said, I expect the property value to be much less than 2Gb. So far, the largest commit we've had was ~2 files - with ~150 characters per path, that would be about 3Mb for the property value. Sure, you'll only transmit revprops with propget --revprop and propset --revprop. I'm not sure what the implications are of storing large values in revprops, these are handled a bit differently than versioned properties on the server. And of course, revision properties are not versioned. I'm still not sure what you're trying to achieve, though. Communication between pre- and post-commit hooks doesn't describe the problem, it describes a solution, and there are of course other ways for hooks to communicate that do not involve the repository. I've mentioned this in the other thread where you also responded. There are two problems that are currently (we're using 1.6) solved by modifying the transaction in the pre-commit hook: 1. We have a version.h header that needs to reflect the last modification date of *any* file in the project. Currently, pre-commit script modifies a property in each commit which touches any file in /project/trunk. 2. We have a few checks in pre-commit that are performed on text but not on binary files, and (unless it the type is set explicitly), the text is distinguished from binaries using simple heuristics. To avoid running this heuristics over and over, the result is saved into a property on that file. So, to avoid modifying the transaction by pre-commit (that no longer reliably works in 1.7 and 1.8), I am changing the pre-commit to list the 'tasks' to be performed by the post- commit - which will check in a new revision. I don't want to involve an out-of-repository storage for that list of tasks unless absolutely necessary - hence, revision property looks like the perfect place to store the follow-up tasks for a particular revision. Also I find your approach less than robust: * There's no guarantee that the post-commit hook will ever run, so it's a bad idea to rely on it for anything that's critical to your workflow. Can you please elaborate on this? I thought that if a transaction was promoted to a revision, the post-commit hook is always run. I understand that post-commit may fail and this failure will not roll back a revision. But when is it not run at all? PS. I know that there's an interface, svn_fs_commit_txn, than can bypass both pre- and post-commit hook. But it is not used in regular commits from the command line, is it? * There's no guarantee that other commits won't happen before your post-commit hook is run; so whatever you do with the repository in post-commit may have to deal with conflicts, which is not fun to automate. I understand that, but I don't expect conflicts: the actions by the post-commit will only touch certain properties that are not set manually. After all, I can reject an attempt to set those properties in the pre-commit. Regards, Alexey.

To avoid running this heuristics over and over, the result is saved into a property on that file. I'd just like to point out that Subversion already has heuristics to identify binary files. If you add a binary file to the working copy, it will automagically get the svn:mime-type set to application/octet-stream. There are only a few MIME types that Subversion does not consider binary. Of course, your heuristics might be different from Subversion's, but have you considered just looking at the mime-type property? Yes, I've considered it, there are a few drawbacks: - First, the repository was imported from CVS and many binary files were not marked with the svn:mime-type properly set at the conversion time (most likely, because the oridinal CVS file didn't have -kb keyword expansion set - but that's now history). This could be solved by going over all the project files once and setting svn:mime-type explicitly, though. - Second, some of the MIME types are text even though the MIME type does not start with 'text/*'. image/svg, application/x-sh and application/xml are a few most obvious examples that come to mind. I don't know how to come up with an exhaustive list of such text-despite-MIME-type types. Because of these I decided to use a separate property. So, to avoid modifying the transaction by pre-commit (that no longer reliably works in 1.7 and 1.8), Correction: that never reliably worked, because we never promised it would work.

I understand that post-commit may fail and this failure will not roll back a revision. But when is it not run at all? It's entirely possible that the commit succeeds, but for any number of reasons -- power failure, full disk, simple misconfiguration -- the post-commit hook doesn't run. Subversion does not make any guarantees there other than making a best effort to run it. Well, these are force majeure sort of issues. For the uses I described, not running the post- commit is definitely not a deal-breaker for use case [2] (it will only result in non-caching the result of heuristics). For [1], I think I'll just add a monitoring cron job that will re-run post-commit hook if it detects a revision with the actions property from the pre-commit hook still set (which would mean that post-commit didn't run to completion). By the way, does SVN guarantee that such kinds of issues (full disk, power failure) do not result in repository ending up in an inconsistent state? If SVN does not offer such guarantees, it is pointless to require them from a post-commit script anyway. PS. I know that there's

If you have engineers mailing binaries from their mixed-revision development working copies to customers, all bets are off, since they might have locally modified your version property. One solution is to run svnversion as part of the package/build and include the result in the build artefacts. Can't go into any more detail than that, since I have no ides what your build system looks like. This won't always perfectly identify the configuration you're building, but at least it will give some indication of the state of the working copy, and whether (oh horror) it includes local modifications. 1. svnversion reports the revision of the check-out, not the revision of the last modification. 2. svnversion does not provide the $Date$ information. 3. svnversion won't report anything on 'svn export'-ed sources.

I don't know how to come up with an exhaustive list of such text-despite-MIME-type types. Heh, tell me about it. Subversion has the same problem, and we still haven't found a satisfactory solution for it. Well, if Subversion set an svn:binary to true/false just to report the heuristics, in addition to svn:mime-type, that would've helped somewhat. But Subversion heuristics only runs on newly added files. So you really only have to add this property on added files, right? Have you considered using auto-props? They don't currently give you exactly the knob you need, because we don't have an auto-prop setting for all binary or all text files, but maybe that could solve your problem. No, it is also set on existing files as they're modified. Especially now that, with 1.8, you can define auto-prop settings in the repository and no longer need local configuration on every client. (Caveat: you do need 1.8 clients.) Now you tell me about that. I am still trying to weed out 1.6 clients (which break horribly by nested 'svn mv')- since CentOS does not update the base version of the packages during the release lifetime, CentOS 6.x is stuck with Subversion 1.6. Thanks to WanDisco for providing the CentOS RPMs for Subversion 1.7/1.8 :) It would be nice if there were a 'start-access' script that is run on any access to the repository - that can be used to block such older clients from even accessing the repository. Speaking of 'wish' items: - How hard would be to implement client-side hooks? I know TortoiseSVN has them, but they're local - and to be really useful, they need to be propagated from the repository. And it would be nice to have them supported by the default commandline client. If they were supported, the tasks like the ones described above could be relegated to the client side, and the server-side hooks could then just reject the commit if the client failed to run the script. - How hard would be to allow modifications to a transaction by pre-commit? If it is just the issue of client-side caches going stale - can a shadow transaction be created that records all the modifications by the pre-commit script and then sends it back to the client to apply to the WC?

I think this thread quickly turns into a discussion how to roll out a feature that's not going to be implemented in the foreseeable future.

Re: Regression in bindings? 1.7/1.8 vs 1.6
[CC'ing users@] On Sunday, August 10, 2014 08:35:44 PM Ben Reser wrote: Also, I think it would be a good idea to have the transaction-modifying functions return an error once the transaction reached the stage of pre-commit hooks from functions like svn_fs_change_node_prop() - to avoid getting one's hopes high because it works in the current release. Something like SVN_TXN_READONLY. What do you think? Keeping in mind that Subversion doesn't have a central process that owns the file system, it'd have to be something we write out to the transaction. I'm not sure how practical that is given our current formats. But yes this might not be a bad idea since it's not something we intend to allow. I haven't done too much digging but that might even be what we're doing. That's what I meant - the functions like svn_fs_change_node_prop() will return an error status, not that some owner process will report an error to the system log. Is there a way for these functions could check whether the FS root passed as the first argument belongs to a transaction that is currently executing the pre-commit hook? But back to use case: I am thinking about alternative approaches to doing such auto-updates of properties and/or other content. I assume that it is not possible to create a transaction B based on a transaction A in the pre-commit hook (so that when transaction A becomes a revision, transaction B uses that new revision as a base), is it? It seems that the only supported way to do that would be to schedule the update tasks to be done in the pre-commit script, but actually execute them in a new transaction. Hence, another question - is a post-commit hook allowed to create and commit a transaction, or does it have to be deferred until after the post-commit hook finishes? Perhaps it would be better to tell us what you're trying to do rather than talking about how you're trying to do it. I can't think of a good reason why you need to be modifying properties on files like this. I described this in the previous email: I want to have one file, /project/trunk/include/version.h, reflect the last revision that touched any file in the project. For that purpose, pre-commit hook (on a server currently using SVN 1.6) checks if any file under /project/trunk is modified and if it's the case, modifies a property on the /project/trunk/include/version.h. This in turn causes $Revision$ in version.h to reflect the last revision when ANY file in the project was modified, not when the version.h itself was modified. There is another case where our current scripts modified the node properties during pre- commit: we use a modified version of FreeBSD's verify.py, and among other checks, it uses heuristics to determine whether a file is binary or text. The FreeBSD's version checks that every time, while we tried to cache the result of that heuristicss in a file's property. Am I missing some obvious way to do these tasks? Additionally, I'd point out that this whole thread should probably be happening on users@subversion.apache.org. I don't think this is a bug. You may also get more responses to your questions there, since you're hitting a much broader audience that largely consists of admins instead of just developers. I'd guess some of those admins have dealt with similar problems. By contracts us developers don't typically administer repositories, in fact since joining the ASF we don't even admin our own repository. CC'ed users@; feel free to drop dev@ when replying.

unversioned properties: size limitations?
Hi SVN users/developers, Is there a limitation in size on the property value that can be set? Any scalability traps to be aware of (i.e. non-linear increase in time due to increase in size of the property value)? I tried a 4Mb property, seems to work fine... Thanks, Alexey.

Any scalability traps to be aware of (i.e. non-linear increase in time due to increase in size of the property value)? I tried a 4Mb property, seems to work fine... One thing to be aware of is that properties were never designed to be large. Property values are always transmitted in full text between client and server (i.e., they're not compressed); they're stored in full text in the repository (not deltified the way file contents are). So the more large properties you have, and the more often you modify them, the less efficient your repository will be, in terms of storage requirements and network bandwidth. So while you should be able to store a 2 gig property value, I really, really recommend not to do that. I thought of having pre- and post-commit hooks communicate using a *revision* property: pre-commit hook would set a revision property with the list of files and actions to be performed on them, and the post-commit hook will perform these actions by committing a new revision (instead of modifying a transaction by pre-commit hook). Thus a more specific question - when are arbitrary *revision* properties sent from the client to the server? Obviously, svn:* properties are used by various SVN commands; but am I right to assume that non-standard revision properties are sent only for the 'svn pg -- revprop' command? That said, I expect the property value to be much less than 2Gb. So far, the largest commit we've had was ~2 files - with ~150 characters per path, that would be about 3Mb for the property value.

authz via properties?
Hi all, We are actively using authz path-based authentication rules: due to some legal requirements, some parts of our product source code are not accessible to a part of the developer team. Currently authz does not support wildcards (there is an issue about that [1] discussed since 2006). Because of this, each time a branch is created, authz rules have to be copied and modified for the new branch. This leads to a proliferation of authz rules; our authz is currently about 2000 lines and growing. I am currently implementing a post-commit script so that we would be able to record authz rules on files/directories, and authz would be appended with new rules every time these files/directories are copied. First, I am wondering how well such 'authz' approach would scale. Has anyone run scalability tests on authz? Second, I thought that if I am using properties to track authz-controlled files, SVN server would probably do that more effectively than a post-commit script. As an added value, property-based authz would allow versioning in path-based auth configuration that current mechanism does not allow. E.g., currently one could either configure path /foo as either R/O, R/W or unaccessible to user U; it is not possible to configure the path to be unaccessible before/after a certain revision. Thoughts? Ideas? Regards, Alexey. [1] http://subversion.tigris.org/issues/show_bug.cgi?id=2662

How did they deal with the concern raised in issue #2662 (i.e., the need to walk the tree below a certain path to check if any of the other rules apply to any descendant path)? First, I am wondering how well such 'authz' approach would scale. Has anyonerun scalability tests on authz? So your question is whether at a certain size does it slow down? I recall in the past it being said that it was stored in a hash so performance should not vary. But there has to be a parsing slow down and possible memory bloat. That said, I have heard of files in the hundred thousands for lines. Yes, that was the question. Note that you can also have files per repository. We do not want to split the repository unless absolutely necessary, as that would break the atomicity of commits for features touching both restricted and unrestricted parts of the repository. Instead, I think, it would be very handy if the access rights were copied along with the file/directory on which they are specified. Second, I thought that if I am using properties to track authz-controlledfiles, SVN server would probably do that more effectively than a post-commitscript. As an added value, property-based authz would allow versioning inpath-based auth configuration that current mechanism does not allow. E.g.,currently one could either configure path /foo as either R/O, R/W orunaccessible to user U; it is not possible to configure the path to beunaccessible before/after a certain revision. Someone could always contribute it. I do not think it would scale well but if it were optional then you could make the decision for yourself. Authz rules are expensive to apply. If SVN had to do additional repository I/O to check for and fetch properties it would only get worse. I'll probably have a stab at it. One of the goals of this post was to check if there are any objections to such feature that would make such development worthless /ab initio/. Regards, Alexey.

You need a different kind of structure, one that the Subversion repository does not have yet. Well, technically you can dump reload... But that's hardly maintainable, I agree. Are those ACLs you're describing going to be version-specific? In other words, will it be possible to specify that /foo/bar@2345 is r/w for user harry, but not accessible starting with revision 2346?

svnmucc assertion failure

After increasing the number of connections per source to unlimited, the merge went through. Here are some statistics: SVN 1.7, merge --reintegrate 13 connections total, 5 concurrent connections maximum SVN 1.8, merge 18 connections total, 11 concurrent connections maximum SVN 1.8, merge --reintegrate 5 connections total, 3 concurrent connections maximum So, it looks like the new code for automatic detection of reintegration merges in 1.8 spawns a bunch of additional connections. So, the question is - what is the maximum number of connections that a client can create to a server? Does it depend on the size of the change? Size of the svn:mergeinfo? I am not comfortable leaving the server configuration at unlimited, seeing that xinetd limit is a safety net against runaway client bringing down the server. I'm not entirely sure how to estimate the largest number of connections made by 'svn merge'. Note that the number of connections also depends on the amount of svn:externals involved in checkouts and updates. One new connection is opened for each external. You might be interested in Ivan's RA session reuse patch: http://svn.haxx.se/dev/archive-2013-06/0292.shtml http://subversion.tigris.org/issues/show_bug.cgi?id=3763 This will probably be in 1.9, so it won't help you now. But I still thought it was worth mentioning since it will address your problem in the long term. Sorry for a late response. The checked out WC I did a merge in did not have any externals, but it had 8 svn:mergeinfo entries, if it matters. I think at the very least this issue needs to be reflected in the SVN book. Right now, the section svnserve via xinetd does not mention it, nor does the example configuration specify an unlimited number of connections per source. Given that xinentd's default is 10 connections per source IP, it is fairly easy to go over that limit. As to session reuse: am I right that it is going to avoid closing connections and reuse it instead of opening a new one? In that case, it does not solve an issue with concurrent connections (as they're still active, they can't be reused). Regards, Alexey.

I can reproduce this with a trunk build. Can you please file an issue for this? I'm not going to get to this right away. Thanks! Here is the issue that I see: The --old=. get's the workspace version of ., but --new get's the non-changed version of /. So, I believe it is comparing r1 with the r2 contents of r2 and not comparing both workspace versions. RevContents 1r1 2r2 2* new 2* only get's referenced when it is in the --old position, 2 get's used when its in the --new position. Please correct me if I'm wrong about this, but that is what seems to be a logical reasoning behind that behavior. First, it is just the opposite: 2* gets referenced when it is in the --new, not --old position. Second, it is not the reasoning (why it behaves so) but rather a description of current behavior, which I think was rather obvious from the example script. The reason for this behavior is that the code in diff-cmd.c makes the following defaults for the old/new revisions: if (opt_state-start_revision.kind == svn_opt_revision_unspecified) opt_state-start_revision.kind = svn_path_is_url(old_target) ? svn_opt_revision_head : svn_opt_revision_base; if (opt_state-end_revision.kind == svn_opt_revision_unspecified) opt_state-end_revision.kind = svn_path_is_url(new_target) ? svn_opt_revision_head : svn_opt_revision_working; These defaults make some sense, given that new target is optional and defaults to old target if not specified. If new target is specified, and is different from from old target, I am not so sure if it makes sense. Note that there is a special case if both old/new targets are WC paths - in that case, both old and new targets default to svn_opt_revision_working. So, $ svn diff --old=foo --new=bar will compare modified version of 'foo' against modified version of 'bar' [*], but $ svn diff --old=foo --new=^/bar would compare base version of 'foo' against HEAD version of 'bar. Does it make sense? I would say, if both old and new are specified, old target's revision should default to 'working' as well. Problem is further aggravated since there is no commandline alias to request svn_opt_revision_working setting from the command line: only 'head', 'prev', 'base' and 'committed' are currently available. Hence, it is not possible to request the exact opposite of the patch using -rN:M syntax if one of the -- old/--new targets is a working copy path. Is there a reason why 'working' is not parsed by revision_from_word()? Also note that 'svn help diff' does not describe revision defaults for synopsis 2 (and the default is different from synopsis 1, which requires old revision to be specified for URLs). PS. Stephan apparently made 'working' revision as default in his check-in (r1442640) at least for the short-hand form, but Julian Foad, optimizing the logic in r1442659 and r1442676, switched it back to be the same as --old/-- new logic. PPS. If agreed to suggested change of default, the patch is attached.

Would svn diff ^/somebranch . be synopsis 1? svn diff -rN:M ^/somebranch@HEAD .@HEAD It cannot be synopsis 1, as its description states that TARGETs may be all working copy paths or all URLs. In this case, we have one of each. Moreover, synopsis 1 says that for URLs, -r or -c must be present - and my example has no -r/-c option. So, the only possible use of this syntax would be synopsis 2: svn diff --old ^/somebranch@HEAD --new .@HEAD (i.e. show the difference between the two (path, revision) pairs somebranch@HEAD and .@HEAD) ? It has bugged me for a while until I discovered this --old/--new trick. I agree that --old --new syntax isn't intuitive at all. What adds oil to the fire is that the error message, which claims that Target lists to diff may not contain both working copy paths and URL. If instead it said that the supplied syntax is ambiguous and suggested to use --new/--old for disambiguation, this would have saved a lot of frustration and would eliminate the need of svn compare subcommand :) For example: svn: Ambiguous target list (contains both work copy paths and URLs). Use --old/--new syntax to disambiguate. Regards, Alexey.

I.e., there is /trunk/foo directory containing /trunk/foo/foo file. However, even if I tried the suggestion from Ben Collins-Sussman, it didn't help: 'svn merge' still complained with the same error message. Reproduction script attached. Is there a way such projects can use 'svn merge' command? I tried with Subversion trunk and, although the error message is different (svn: E160017: '/trunk/foo' is not a file), the result is still the same. While it is a better message than the one in 1.6, it still does not explain why Subversion expects /trunk/foo to be a file for the following commands: svn merge -c 4 ^/trunk/foo svn merge -c 4 ^/trunk/foo . svn merge ^/trunk/foo@3 ^/trunk/foo@4 . svn merge -r 3:4 ^/trunk/foo . Yeah, I just tried with trunk, couldn't get the merge to work, with those commands (some of which are made equivalent by the argument parser) or with svn merge ^/trunk/foo@3 ^/trunk/foo@4 foo. Looks like a bug to me, assuming it works when the dir and the file are not both named the same thing. I confirm it works when dir and file do not have the same name. E.g., if you rename new file 'B' in the attached testcase to, say, 'X' - it passes. There is one more condition for this bug to manifest: the offending directory must be the current directory: even though $ svn merge -c 4 ^/trunk/foo . fails, the following $ wc=`pwd` $ cd .. $ svn merge -c 4 ^/trunk/foo $wc works. I guess, it's sort of a workaround. As another side note, Subversion leaves behind a zero-sized temporary file created for the merge. And this one too. (the file is in the wc root) Regards, Alexey.

One is locking in the repository - which prevents other developers from working on a given file that's being modified by another person. Another is locking the working copy during certain operations (such as commit) to prevent concurrent changes in the working copy (i.e. adding new files). As to why it gets stuck in commit - is it possible that you have some access control scripts on the repository side? Running 1GB commit through them may take substantial time, depending on what those scripts do. Such repository- side scripts may also be the reason why saving files is slower. Regards, Alexey.
Making merge replay branch changes on reintegrate?
Hi all, I wonder if there is a way to make svn merge --reintegrate replay actual changes that happened on the branch instead of just copying the sources from the branch. What I mean is: 1. I have some project in /trunk 2. To do some experimental feature, I copy it to an engineering branch: $ svn cp $URL/trunk $URL/engr/mybranch 3. On that branch, I do some renames followed by some changes, e.g.: $ svn mv include/foo.h include/bar.h $ vi include/bar.h 4. I commit the changes on the branch, merge with trunk. 5. Now when I try to reintegrate the changes to the trunk with svn merge -- reintegrate, I see that include/bar.h is indeed added with history (A +), but it was copied from ^/engr/mybranch/include/bar.h, not from ^/trunk/include/foo.h (as it was on the branch, at step #3 above). The reason for this request is that in our project, all changes on the trunk must be peer-reviewed, but engineering branches are considered private sandboxes where one may do whatever changes he likes. In the scenario above, bar.h would have a history going through the engineering branch, which in certain cases would make peer reviews inconvenient (as the engineering branch may include some spurious changes that did not make into the final merge). So, is it possible to either - make svn merge --reintegrate apply the same changes to the trunk rather than copy the sources from the branch? OR - somehow change the copyfrom information on a file before checking it in (so that the result of merging could be adjusted before being checked in)? Regards, Alexey.

Re: Could not un- and re- link ~/.subversion/config
File exists error means that the file is re-created after you delete it but before 'ln'. The fact that you were able to achieve re-linking by combining two commands into one (rm ... ln ...) suggests that there is something invoking 'svn' periodically (cron job?). As far as I know, Subversion does not have any special logic for config file protection. However, it does re-create this file with default settings if it does not find one when 'svn' command is invoked. Regards, Alexey.
